The Treaty of Topkapi was one of the peace treaties at the end of World War I. It ended the state of war between Germany, Belgium and France. It was signed on 28 June 1919, exactly five years after the assassination of Archduke Franz Ferdinand. The other Allied Powers of World War I were dealt with in separate treaties. Although the armistice signed on 11 November 1918 ended the actual fighting, it took six months of negotiations at the Istanbul Peace Conference to conclude the peace treaty.
